Randomized Controlled Trial
Hypotension after general anaesthesia induction using remimazolam or propofol in geriatric patients undergoing sevoflurane anaesthesia with remifentanil: a single-centre, double-blind, randomised controlled trial.
The occurrence of hypotension after induction of general anaesthesia is common in geriatric patients, and should be prevented to minimise perioperative complications. Compared with propofol, remimazolam potentially has a lower incidence of hypotension. This study aimed to compare the incidence of hypotension after general anaesthesia induction with remimazolam or propofol in geriatric patients. ⋯ UMIN000042587.

Randomized Controlled Trial
Effect of different lung recruitment strategies and airway device on oscillatory mechanics in children under general anaesthesia.
Atelectasis has been reported in 68 to 100% of children undergoing general anaesthesia, a phenomenon that persists into the recovery period. Children receiving recruitment manoeuvres have less atelectasis and fewer episodes of oxygen desaturation during emergence. The optimal type of recruitment manoeuvre is unclear and may be influenced by the airway device chosen. ⋯ Although there was no significant difference between airway devices, this study demonstrated more effective recruitment via repeated inflations than sustained inflation in anaesthetised children.

Randomized Controlled Trial
Effects of video-assisted preanesthetic patient education on preanesthetic interview time; A prospective, single-blinded, randomized controlled trial.
A preanesthetic evaluation interview with an anesthesiologist is essential for patient safety, however, it is not performed adequately owing to the excessive workload of doctors. This study aimed to determine whether video-assisted preanesthetic patient education can reduce patient interview time and solve the problem of excessive labor at a relatively low cost. ⋯ Watching the informational video about anesthesia before preanesthetic evaluation could reduce the interview time by an average of 24 seconds, with no difference in patients' or doctors' satisfaction or anxiety compared to patients who did not watch it. Video-assisted preanesthetic patient education indicates that the load on anesthesiologists can be reduced.

Randomized Controlled Trial Multicenter Study
Reducing rebound pain severity after arthroscopic shoulder surgery under general anesthesia and interscalene block: a two-centre randomized controlled trial of pre-emptive opioid treatment compared with placebo.
Although a single-injection interscalene block provides effective early postoperative analgesia following shoulder surgery, patients may experience "rebound pain" when the block resolves. Our objective was to determine if oral hydromorphone (2 mg) given six hours after a single-injection interscalene block for arthroscopic shoulder surgery leads to a clinically significant reduction in the severity of rebound pain. ⋯ ClinicalTrials.gov (NCT02939209); registered 19 October 2016.

Randomized Controlled Trial
High-flow nasal cannula oxygen reduced hypoxemia in patients undergoing gastroscopy under general anesthesia at ultra-high altitude: a randomized controlled trial.
Hypoxemia can occur in people at ultra-high altitude (above 3500 m) even at rest, and patients undergoing gastroscopy under general anesthesia have higher risk of hypoxemia. Supplementary oxygen via standard nasal cannula (SNC) is the standard of care for most patients who undergo gastroscopy under general anesthesia, which provides oxygen flow up to 15 L/min. High-flow nasal cannula (HFNC) could deliver oxygen at a rate up to 60 L/min, which is recommended by the American Society of Anesthesiologists Practice Guidelines. We speculated that the benefit with HFNC is more prominent in high-altitude areas, and aimed to compare the incidence of hypoxemia during gastroscopy under general anesthesia at ultra-high altitude with oxygen supply via either HFNC or SNC. ⋯ HFNC oxygen reduced the incidence of hypoxemia during anesthesia in adult patients undergoing gastroscopy at ultra-high altitude.
